Title: Production of coke for metallurgy
Inventor: INOUE KEIZO
IPC: C10B39/02
Filed: 1992-05-06
Abstract: PURPOSE:To obtain the coke for metallurgy enhanced in the cold strength and lowered in the reactivity with hot CO2 by charging red-heated coke into the upper region of a reactor, blowing a hydrocarbon into the reactor for its reaction, burning the discharged unreacted hydrocarbon and subsequently passing the produced cooling gas into the lower part of the reactor. CONSTITUTION:Red-heated coke is charged from the upper opening 2 into the upper first region 4 of the reactor (cooling tower) 1 of a dry type quenching device having the upper region 4 and the lower second region 6. A hydrocarbon (e.g. soft pitch) 11 is intermittently sprayed from the spray nozzle 9 in the first region 4 with a press-spraying pump 12 and passed downward from the region 4. The hydrocarbon is pyrolyzed with the red-heated coke, and the produced decomposition gas containing H2, CH4, etc., is sucked with a circulation fan 19, taken out of the upper flue 7 and subjected to a combustion treatment in a combustion tower 13. The exhaust gas after the combustion treatment is subjected to the removal of dusts with a dust collector 21 and subsequently passed from the lower blowing opening 10 into the lower second region 6 as a cooling gas through the upper steam boiler 14 and a cyclone 17 to obtain the coke for metallurgy.

Filed: 1984-06-02
Abstract: A propulsion device comprises two symmetrical wheels 14 mounted in the same plane for rotation about parallel axes 32 at right angles to the plane and driven by a device 40 synchronously in opposite directions. Each wheel carries a pair of gearwheels 26,27 which rotate around the axis of the wheel with the wheel and support eccentrically a pair of planet masses 33, 34. The masses 33, 34 are arranged such that their distance from the axis 32 of rotation of the wheel increases and decreases under control of the gear wheels 26, 27. At a position immediately prior to the maximum distance of the planet from the axis, an electromagnetic device 38 restrains outward movement of the planet mass 26, 27 so that when released the planet mass 26, 27 provides whiplike action inducing a resultant force in a direction at right angles to the plane containing the axes 32 of the wheels 14.

Filed: 1994-04-28
Abstract: PURPOSE:To reduce the writing number of times of a non-volatile memory by renewing the set data from a setting means to store the same in a volatile memory and writing the set data in the non-volatile memory when an operation mode becomes a stand-by mode. CONSTITUTION:Control is started at each time when the timer interruption signal of the fine time from a timer 52 is outputted to a CPU 51. When printing processing is not performed at the time of an operation mode and a count value counting the interruption number of times made incremental is equal to a constant becoming a stand-by mode, the set data stored in the set data memory of the control memory of a DRAM 60 is read to be written in an EEPROM 54 and a stand-by mode flag is set to set the stand-by mode. Therefore, since the set data of the set data memory is written only at the time of the stand-by mode, the wiring number of times to the EEPROM 54 can be reduced.

Moreover, a diode 9 is conductive and a spot killer pulse is charged up in a hold capacitor 7 and the brightness of an output signal of the clamp circuit 2 is increased. After the boosted video signal is amplified, the amplified signal is fed to a cathode of a CRT and consumed before the CRT is completely stopped.

Title: Forming method of semiconductor crystallized film
Inventor: YAMAGUCHI NORITOSHI
IPC: H01L21/263
Filed: 1990-04-28
Abstract: PURPOSE:To improve the heat distribution of a semiconductor thin-film at a time when laser beams are applied, and to form a crystallized film having large grain size by scanning laser beams having a beam diameter larger than the line width of a metallic layer along the metallic layer and crystallizing the semiconductor film. CONSTITUTION:A linear metallic layer 2, a foundation layer 3, an amorphous or polycrystalline semiconductor film 4 and a protective film 5 are formed successively on a substrate 1, and the film 5, the film 4 and the layer 3 are removed insularly through etching. The insularly etching-removed film 14 is irradiated with laser beams from the upper section of the film 5 while scanning laser beams along the linear metallic layer 2, thus melting and solidifying and crystallizing the film 4. Since the layer 2 having large thermal conductivity is formed at approximately the central section of the lower layer section of the film 4 at that time, the heat of the film 4 heated by laser beams is dissipated from the section of the layer 2, thus cool-ing the film 4 from the central section of the film 4 and solidifying the film 4. Accordingly, a crystallized film having large grain size can be acquired stably.

Title: Power source for dot matrix liquid crystal display
Inventor: JIYAN FUREDERITSUKU KUREERU
IPC: G02F1/133
Filed: 1990-05-01
Abstract: PURPOSE:To improve the visual performance of a large-sized dot matrix liquid crystal display device by detecting a current which is supplied from a segment driver power source, inverting and amplifying the current, and applying it to a common driver power source with capacity coupling. CONSTITUTION:Currents which are supplied from segment power sources V1, V3, V4, and VEE are detected by a series of small resistances (r), etc., and potentials generated on the respective resistances (r) are reversed in polarity and amplified by a normal inverter amplifier A. The signal supplied by the inverter amplifier A is fed back to the output lines of common power sources V2 and V5 corresponding to a nonselecting state. For example, the signal is applied to capacitors C connected to the output lines of the common power sources and those output lines are provided with resistors R in addition to the capacitors C. Thus, when opposite segment electrodes are switched on the whole, an effective current which can be supplied to a common electrode is increased greatly. Consequently, the attenuation time of parasitic pulses of a common signal is shortened greatly. Consequently, the crosstalk when many gray levels are displayed can be reduced.
